The supply for the switch
I30 is controlled by the ignition
(INT) from the line for fuse F37 of the underdashboard control unit
B2: when the brake pedal is pressed, the switch closes and sends
the 'N.A.' signal to the Body Computer M1, pin 2 of connector F.
The 'ignition ON' signal (INT) for the switch
H1 reaches the underdashboard control unit B2 at pin 11 of connector
H and from there moves on to the Body Computer
M1
(pin 9 of
connector F).
The Body Computer
M1
controls the
supply for the brake lights in the light clusters
F30
(left)
F31 (right) from pins 32 and 33 of connector E.
The Body Computer
M1
is connected,
via the CAN line, to the instrument panel
E50
to manage
the 'lights failure' warning light if there is a failure in the
circuit.
The switch
I30 directly controls the
centre rear light cluster F40 via the underdashboard control unit
B2, pin 5 of connector D
